Simulation of tissue heating by magnetic fluid hyperthermia
Objective: Magnetic fluid hyperthermia is a technique in which thermal energy is generated by magnetic nanoparticles (MNPs) that are excited by an alternating magnetic field (AC field). During hyperthermia, in-vivo monitoring of elevation of temperature relies on invasive insertion of conventional thermometers, or employment of thermo-sensitive cameras that lack high precision....
متن کاملComparison of forced-air warming and resistive heating.
BACKGROUND Perioperative hypothermia is common during anesthesia and surgery and is accompanied by several complications. Forced-air warming is recognized as an effective procedure to prevent hypothermia. The aim of this study was to compare a resistive heating device with a forced-air warming device. METHODS Prospective randomized trial. SETTING heat transfer laboratory of a University hos...
متن کاملWarming by resistive heating maintains perioperative normothermia as well as forced air heating.
BACKGROUND Even mild perioperative hypothermia is associated with several severe adverse effects. Resistive heating has possible advantages compared with other active warming systems because it can heat several fields independently. To assess this new warming system, we measured core temperature in patients during surgery who were warmed with circulating water mattresses, forced air covers or r...
متن کاملResistive-heating and forced-air warming are comparably effective.
UNLABELLED Serious adverse outcomes from perioperative hypothermia are well documented. Consequently, intraoperative warming has become routine. We thus evaluated the efficacy of a novel, nondisposable carbon-fiber resistive-heating system. Twenty-four patients undergoing open abdominal surgery lasting approximately 4 h were randomly assigned to warming with 1) a full-length circulating water m...
متن کاملHeating magnetic fluid with alternating magnetic field
This study develops analytical relationships and computations of power dissipation in magnetic fluid (ferrofluid) subjected to alternating magnetic field. The dissipation results from the orientational relaxation of particles having thermal fluctuations in a viscous medium. r 2002 Elsevier Science B.V. All rights reserved.
